Abstract

La présente invention se rapporte à un procédé de fonctionnement d'un système permettant de traiter une arrivée de gaz dans un tube prolongateur (5) pendant le forage d'un puits de forage, le procédé comprenant les étapes consistant à faire fonctionner un premier appareil de fermeture de colonne montante (21) pour fermer la colonne montante (5) au niveau d'un premier point situé au-dessus d'une bride d'écoulement (22) agencée dans la colonne montante (5), une conduite de traitement de gaz de colonne montante (47, 48) s'étendant depuis la colonne montante (5) au niveau de la bride d'écoulement (22) jusqu'à un collecteur de traitement de gaz de colonne montante (49), à faire fonctionner un second appareil de fermeture de colonne montante (3) pour fermer la colonne montante (5) au niveau d'un second point situé sous la bride d'écoulement (22), à pomper le fluide dans une conduite d'admission (41) qui s'étend dans la colonne montante (5) au niveau d'un point situé au-dessus du second point mais en dessous de la bride d'écoulement (22), le procédé consistant en outre à faire fonctionner une duse (53, 54) agencée dans le collecteur de traitement de gaz de colonne montante (49) pour garder la pression dans la conduite d'admission (41) ou la colonne montante (5) à une pression sensiblement constante.
